Detailed Description
The present disclosure is further described with reference to the following drawings and examples.
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
The embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict.
Example 1:
as shown in fig. 1, an embodiment 1 of the present disclosure provides an atmospheric corrosivity data compensation method, including the following steps:
when the data loss is within 1 day, the data collected within 2h can be supplemented by using the data of the nearest time point which is pushed forward by the loss time of the equipment.
When the data loss is within 1 day, and exceeds 2h and is less than or equal to 24h, the data at the same time point on the most adjacent day before the loss date is used for filling.
And when the continuous time of data deletion is more than 1 day and less than 1 month, the data at the same time point before the deletion date is used for supplementing.
And if the continuous missing data time of the current site is not less than 1 month, supplementing the data of the same month in the next year.
When short data of the acquisition period is insufficient and the evaluation of atmospheric corrosion and material corrosion resistance is difficult to complete, the following compensation method can be adopted:
the country is bounded by Qinling mountain-Huaihe river, and the regions of Henan and Shandong are north, including North China, northwest China and northeast China. The monthly atmospheric corrosivity ratio is defined as: 5%, 5%, 6%, 8%, 10%, 14%, 14%, 11%, 10%, 7%, 5%, 5% in 1-12 months, respectively.
The country is bounded by Qinling Ling-Huaihe, and the southern area includes Sichuan, Yunnan, Hainan, Taiwan, etc. The monthly atmospheric corrosivity ratio is defined as: the contents of the extract are respectively 4%, 6%, 7%, 10%, 11%, 11%, 12%, 12%, 12%, 6%, 5% and 4% in 1-12 months.
That is, when only 1 or several months of the corrosion data are satisfied for 1 year, the above ratio can be calculated every month in order to quickly complete the atmospheric corrosivity evaluation. When the data is not full-month data, it should be calculated as corrosion occupancy of the day, which is corrosion occupancy per month/day of the month. The corrosion amount per year in a known time is the year-round corrosion amount of the area.
